Mercedes C63 AMG S vs BMW M4 vs Porsche 911 C4 GTS - Launch control drag race

We put hi-tech launch control systems to the test in a range of performance cars to see how effective they are in a standing start. We've got the Porsche 911 Carrera 4 GTS, BMW M4 and Mercedes-AMG C 63, but in the interest of fairness, we've included a VW Polo BlueMotion, too!
